Definitions
- the present invention is directed to a method and apparatus for quickly and effectively conditioning soil to make it workable for construction projects and other work projects. More specifically the present invention changes the moisture content of soil at a work site.
- Construction projects that cover an area of ground require a stable foundation. Construction projects that fit into this class of projects include roads, airport runways, warehouses, and earth works such as levees, dams, and landscapes having steep grades. Other construction projects have this need as well. A subsidence of the earth beneath all of these types of projects causes immense damage and can be catastrophic to the point of risking lives, so the stable base is a must.
- the ground is compacted to form a layer of solid, stable, earth to support the structure over the life of the structure.
- This compaction may take multiple iterations where compacting equipment passes over an area to compact the soil.
- soil in place is compacted and then additional soil is brought to the location and compacted on top of the original, compacted soil.
- the process necessarily requires high repetitions of the process of adding soil and compacting.
- the added soil has specific characteristics for specific properties. Clay, for example, is frequently used as a constituent ingredient for its properties.
- the soil compaction process is highly sensitive to the moisture content level in the soil. If the moisture content is too high, the compaction process does not work. This can essentially halt major construction projects until the issue is addressed which results in huge costs in time and money.
- One method is removing earth from a location and spreading it for drying. Once the spread earth is sufficiently dry, it is moved back to the location and compacted.
- Another method is mixing in other components such as lime, etc. to reduce the moisture content. The different methods are not mutually exclusive. Once the moisture content of the soil is tested and meets the required low moisture content, the compaction process can begin.
- Embodiments of the present invention provide an additional method for controlling the moisture content of soil at a construction site.
- Embodiments of the present invention create a flow of air and add heat to the air by burning fuel. At least some embodiments burn the fuel directly in the flow of air.
- the heated air is directed toward the ground and a soil mixer.
- the soil mixer churns the soil to expose the soil to the heated air.
- the soil is mixed to the depth reachable by the mixer and in some embodiments, the mixer will propel the soil up into the air into the stream of heated air which effectively exposes a greater surface area of the soil to the heated air.
- Some embodiments of the soil conditioner utilize a drying chamber to contain the mixing process.
- the mixer is powered by the vehicle towing the soil conditioner. This can be accomplished by a power-take-off shaft on the towing vehicle. Other power requirements onboard the soil conditioner may be satisfied by an onboard generator for controls and for the blowers creating the flow of air.
- Embodiments of the soil conditioner can condition the soil in the location where the soil is to be used and compacted. This removes the need for spreading the soil for drying. Multiple passes of the soil conditioner can be used when needed.
- the mixer of the soil conditioner can also facilitate the mixing of additives to the soil.

Abstract
Description
- This application claims the priority benefit of U.S. Provisional Patent Application Ser. No. 62/154,050, “Soil Conditioning Apparatus,” filed Apr. 28, 2015, which is hereby expressly incorporated by reference herein in its entirety.
- The present invention is directed to a method and apparatus for quickly and effectively conditioning soil to make it workable for construction projects and other work projects. More specifically the present invention changes the moisture content of soil at a work site.
- Similar to buildings that require a stable foundation to support the building for the duration of the life of the building, construction projects that cover an area of ground require a stable foundation. Construction projects that fit into this class of projects include roads, airport runways, warehouses, and earth works such as levees, dams, and landscapes having steep grades. Other construction projects have this need as well. A subsidence of the earth beneath all of these types of projects causes immense damage and can be catastrophic to the point of risking lives, so the stable base is a must.
- To establish this stable base at large area construction sites, the ground is compacted to form a layer of solid, stable, earth to support the structure over the life of the structure. This compaction may take multiple iterations where compacting equipment passes over an area to compact the soil. In some cases, soil in place is compacted and then additional soil is brought to the location and compacted on top of the original, compacted soil. For levees and dams that require a build-up of earth, the process necessarily requires high repetitions of the process of adding soil and compacting. In many cases, the added soil has specific characteristics for specific properties. Clay, for example, is frequently used as a constituent ingredient for its properties.
- The soil compaction process is highly sensitive to the moisture content level in the soil. If the moisture content is too high, the compaction process does not work. This can essentially halt major construction projects until the issue is addressed which results in huge costs in time and money. There currently are methods for adjusting, i.e. removing, moisture from soil at construction sites. One method is removing earth from a location and spreading it for drying. Once the spread earth is sufficiently dry, it is moved back to the location and compacted. Another method is mixing in other components such as lime, etc. to reduce the moisture content. The different methods are not mutually exclusive. Once the moisture content of the soil is tested and meets the required low moisture content, the compaction process can begin.
- Embodiments of the present invention provide an additional method for controlling the moisture content of soil at a construction site. Embodiments of the present invention create a flow of air and add heat to the air by burning fuel. At least some embodiments burn the fuel directly in the flow of air. The heated air is directed toward the ground and a soil mixer. The soil mixer churns the soil to expose the soil to the heated air. The soil is mixed to the depth reachable by the mixer and in some embodiments, the mixer will propel the soil up into the air into the stream of heated air which effectively exposes a greater surface area of the soil to the heated air. Some embodiments of the soil conditioner utilize a drying chamber to contain the mixing process. In some embodiments of the soil conditioner, the mixer is powered by the vehicle towing the soil conditioner. This can be accomplished by a power-take-off shaft on the towing vehicle. Other power requirements onboard the soil conditioner may be satisfied by an onboard generator for controls and for the blowers creating the flow of air.
- Embodiments of the soil conditioner can condition the soil in the location where the soil is to be used and compacted. This removes the need for spreading the soil for drying. Multiple passes of the soil conditioner can be used when needed. The mixer of the soil conditioner can also facilitate the mixing of additives to the soil.
- Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the figures. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purposes of description and should not be regarded as limiting.
- Accordingly, those skilled in the art will appreciate that the conception upon which this invention is based may readily be utilized as the basis for other structures, methods, and systems for carrying out the purposes of the present invention. It is important, therefore, that the specification be regarded as including such equivalent constructions insofar as they do not depart from the spirit of the present invention.
- Furthermore, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially including the practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the invention of the application nor is it intended to be limiting to the scope of the invention in any way.

soil conditioner 10 of the figures is pulled along an area of ground that needs to be conditioned for work. Fuel and air are induced intoburner 42 and the fuel is combusted to heat the air which passes into dryingchamber 43.Soil mixer 60 mixes the soil beneath dryingchamber 43 assoil conditioner 10 moves along the ground which results in reduced moisture in the soil, rendering the soil into a more workable state. This exposes soil as deep beneath the surface asmixer 60 is capable of reaching. In some embodiments,mixer 60 propels soil up into the air within dryingchamber 43. When the soil is propelled into the air, greater surface area of pieces of soil are exposed to the heated air. - Embodiments of
soil conditioner 10 have multiple adjustable parameters to optimize the process. Rate of travel over the ground being conditioned can be adjusted. The rate of air flow intoburner 42 and dryingchamber 43 can be adjusted by varying the speed ofmotors 45. The heat added to the air can be adjusted by the amount fuel introduced intoburner 42. The rate of mixing of the soil can be varied by adjusting the rate of turn ofmixer 60. In some embodiments ofsoil conditioner 10 the rate ofmixer 60 is controlled by varying the rate of turn of the PTO of a towing vehicle. - While specific embodiments have been discussed for the sake of illustrating the current invention, particulars of the description of the embodiment should not be construed as limiting the invention. The apparatus may vary in many ways while still staying within the scope of this specification. For example, the fuel tanks could be moved to a trailer pulled behind a frame carrying the blowers, burner, mixer, and drying chamber. Moving the tanks to a separate trailer would distribute the weight and make the frame carrying the working elements of the soil conditioner lighter. It would also make the fuel source portion of the apparatus interchangeable which is helpful for apparatuses working in the field. Further, the apparatus and method could be adapted to soil stabilizers such as those made by Caterpillar, for example CAT SS-250, CAT RM-500 or built upon a self propelled chassis to create a vehicle dedicated to soil conditioning. Those well versed in the art can see the wide range of applications for such an apparatus with its high degree of adaptability. The independent adjustment of the air blowers, the burner, the rate of soil mixing, and the rate of conveying the apparatus, allows a wide variation of embodiments and operations for the apparatus and methods.
